Tom, I really hate to disagree with you, but humans are subject to the same ultimate law of the universe as everything else in nature. This most basic law says that at some point in time creation will always be offset by destruction. Just like stars are born and stars die, peace is always offset by war and love by hate. Moreover, there is that saying that if something can go wrong it will go wrong. Indeed, it is impossible to have thousands of nuclear tipped missiles on hair trigger alert that can wipe out humanity a thousand times over and not expect some human miscalculation or technical glitch to eventually set them off like a string of Chinese firecrackers.
Now of course this reality gets downplayed by average folks because nature has also hardwired us with a powerful sense of hope, often when there is no rational reason for hope, because without hope life can’t go on. So we keep on pushing forward sometimes against the impossible, or bury our heads in the sand when there are things for which there is no good answers.
Now I’m not a knee jerk pessimist, but I think I pretty much understand humanity’s place in the universe, meaning that with all our marvelous technical creations over the last several centuries containing their own builtin seeds of destruction, we have been living on borrowed time, which can’t go on forever.
